Probabilistic Risk as Political Frame

Treat probabilistic risk assessment not merely as a technical tool but as a political and rhetorical frame that enables continued deployment of risky infrastructure by rendering catastrophic outcomes 'acceptable' in statistical terms. The history of nuclear regulation shows PRA functions as a governance story that shifts debates from moral absolutes to tradeoffs that regulators, firms, and publics must negotiate. — If PRA is a dominant political frame, then how societies accept, audit, and contest high‑consequence technologies (nuclear, AI, biotech) will depend less on raw safety data and more on how risk is narrated, institutionalized, and made legible to publics.
